ofthetype especially designed for loading purposes.

The invention has for its ObJGCt, among other things, to render theimplement highly efficient and expeditious in action and to enable it toperform its work with facility and satisfaction.

A further object of the invention is to provide for carrying out theaforesaid ends in a simple and inexpensive manner and in highlysatisfactory manner.

With these and other objects in View, the

invention consists of certain-instrumentalities and features ofconstruction substantially as hereinafter more fully disclosed anddefined by the appended claims.

In the accompanying drawings is illustrated the preferred embodiment ofmy in vention wherein it will be understood that various changes andmodifications may be made as to the detailed construction andarrangement of. parts without departing from the spirit or scope of theclaims, and in which drawings;

Figure 1 is aside elevation of my invention as when ositioned forloading;

Fig. 2 is also a similar -view showing the device in its unloading ordischarging position; Y

Fig.' 3 is an enlarged fragmental view showing the parts in lockedposition;

7 Fig. 4 is a sectional view taken on the line 4-4 of Fig. 3;

. Fig. 5 is a sectional view taken on the line 55 of Fig. 3; and r Fig.6 is a fragmental detailed view showing more particularly the roll-pivotreceiving slotted opening in a swinging bar member for said pivot, and acurved form of bar member.

In carrying out my invention I provide a suitable bucket or dipper 1, ofany preferred construction as shown or otherwlse enejof. its sides. Thebucket or dipper 1 is suspended between the branches or prongs of abifurcated bar or bail 3 said branches being pivoted to opposite sidesthereof and retained vertically when the bucket or dipper is inhorizontal or filling position, by means of laterally projecting stopsor lugs 4 on the bucket, said branches resting thereagainst as seen inFig. 1. The bail or suspender 3 is extended upwardly and riveted orotherwise secured to opposed spaced plates 5, and has pivoted to itsupper end a pulley-and-block attachment 6, over the pulley of which iscarried'the lifting cable 7 which extends to a winding drum in the cabdistant therefrom, these however not being shown as they form no part ofthe invention and are commonly employed for a similar purpose.

Swingingly held by a pivot or bolt 8, in-

' termediate the spaced plates 5 are opposed bars 9, which may be eitherstraight as shown in F ig, 3, or curved as illustrated in Fig. 6, saidpivot or bolt being passed through and secured to said plates, said bars9 themselves having riveted or bolted arms 11 the function of whichlatter, will be stated presently. The swing bars 9 have journaledtherebetween, at their lower ends, a roll 12, the journal for said rollbeing thereto as at 10, parallel angularly disposed designated as 13 andsuitably secured to the bars 9. v

About in vertical alinement with, and a short distance below the roll12, is a second, small roll 14 which is mounted upon a journal15preferably, in the form of a bolt suitably securedcin the spacedplates 5,'both the roll 12 and the roll 14 being suitably spaced bymeans of washers 16 from having contact with the plates 5 as seen inFig. 4.

The roll 12 has itsjournal held in slotted apertures, 17 the slots 17thereof opening out through the lower ends of the bars 9, as seenparticularly in Fig. 6, and the resultant split terminals of the plates5 can be suitably manipulated to retain the roll in effective frictionalor gripping action or engagement with the part mterposed there- 'betweenand the opposed roll 14 as will be later appreciated.

Suitably secured to the normally upper tical lateral bar 19 and alurality of ad justing bolts 20, 21, 22 is an upwardly curved member orarm 23 resiliently held in operative position by a stout spring-member24. The spring-member 24 is suitably secured in position at itsbase-end, as by a bolt 25, inserted through the parts 18? and forciblyclamping down said base end, as seen in Fig. 3, the remaining portion ofsaid spring 24 pressing against the rear edge portion of the arm 23holding the latter forcibly V in normal position, and yet allowing for alimited rearwardly flexing action thereof. The bolts 21 and 22 arereceived by slots 25, 26 formed in the member or arm 23, and V are atright-angles to each other as relates to their axes as seen articularlyin Fig. 3,

to provide for the sundry adjustments of the arm as in correcting anyvariations arising from the shifting of the position of the arm.

In operation, it will be seen that, the dip per or bucket 1 occupyingthe position indicated in Fig. 1 for loading, it is suitably elevated,with its contents after loading,

through the action of the cable 7 controlled by the loading cab-1e 27winding on a drum located in a cab at a removed point, which are notherein shown. When the dipper or V bucket is being loaded it is pulledtoward the I cab by the loading cable 27, which is connected bybranch-members 28, 29 to the bucket 1 and the swinging or clamping bar9, the branch member 28 being secured clirectly to the bucket, and thebranch-member 29 to the swinging member 9 through the arm 11 as seen inFig. 3. It will be understood, of course, that connection has beenpreviously made between the arm 23 of the bucket 1 and the clampingrolls 12 and 14 of the bar 9 and member 5, respectively as seen in Fig.3, the releasing action of which will be presently described. In furtherexplanation of the loading operation, it is observed that when thebucket or dipper is full the operator releases the cluch (not shown)associated with the loading cable 27 and puts a foot on a brake (notshown) which holds the loading cable taut, while the'hoisting cable 7raises the bucket sufficiently elevated to allow it to be swung to oneside or the other. The operator now releases the foot-brake, holding theloading cable, thus providing for the release'of the lock formed by therolls 12,

14 between which has been clamped the arm 23 of the bucket, and theconsequent dumping of the bucket or dipper. The bucket, perforce, nowtakes a vertical position and is swung back to be again loaded. As thebucket is lowered to assume a horizontal position upon the ground theupper curved end of the arm 23 as seen in Figs. 1 and 3 is received andautomatically clamped between the rolls 12 and 14, ready for therepetition of the above operation.

What I claim is: V 1, In apparatus of the character set forth,

having a clamping rotary element, said suspending member having a rotaryclamping member cooperating with the aforesaid ro-i:

tary member to receive and automatically clamp therebetween said upperterminal of said arm, as the bucket takes its loading position.
